DAYS 1-5 (MAY 29 – JUNE 2)

An unsettled weather pattern is with us for the final few days of May, and the first several hours of June, in keeping with our weather pattern of late. Reiterating good news, pollen counts have been kept lower by frequent rain (good for allergy sufferers) and we have obliterated whatever was left of drought / abnormal dryness across the region. For many, that’s not enough of a consolation prize, but for those folks, I also have some better news – if you have patience. There isn’t much change to the players and their parts in the unsettled weather of the next few days. A warm front moving into the region today is thwarted a bit by a weak wave of low pressure forming on it and passing just southeast of our area. While many areas saw showers in the pre-dawn hours, additional showers can occur today, favoring RI and southeastern MA through early afternoon, after which the rain threat is a done deal for a while. But primary low pressure passing to our north still has to drag another frontal boundary into the region and it will do that tonight into Friday, and not hurriedly either. This boundary will be the focus point for a few showers and possible thunderstorms during the day Friday – right now leaning toward the I-90 / I-95 belts being more likely, with most of the activity occurring during a few hour window in the afternoon. There are many outdoor graduation ceremonies scheduled for Friday evening and I believe most of them won’t encounter any weather-related issues. I’d love to be able to say that front is going to be pulled cleanly through and we clear out for the weekend, but it’s not the case. Two low pressure areas look like they need to move through our area. The first will deliver a bout of rain later Friday night into Saturday morning. The track of the low center is somewhat crucial to how the balance of Saturday turns out. A further east track keeps us on the cooler, cloudier, damp side. A track further west could give us a few hours of drier, warmer weather before a round of showers and thunderstorms followed it. Leaning ever-so-slightly toward the western track scenario but please check updates on this. One final low pressure wave will ripple up the boundary the early hours of Sunday, but I think this one will move swiftly enough so that most of the shower activity with it will occur between late Saturday night and Sunday’s sunrise time. Again check updates on this too. If this prognostication is correct, most of Sunday would turn out decent. Finally, a drier westerly air flow brings nice weather Monday.

TODAY: Mainly cloudy – breaks of sun favor northwest of Boston early – showers / drizzle most likely south of Boston through early afternoon. Highs 62-69. Wind variable to NE up to 10 MPH early, becoming variable to S later.

TONIGHT: Mostly cloudy with a chance of a shower in the evening. Partly cloudy overnight. Patchy fog. Lows 55-62. Wind SW up to 10 MPH.

FRIDAY: Partly sunny. Slight chance of a shower or thunderstorm favoring the I-90 and I-95 belts midday to mid afternoon. Highs 73-80, cooler South Coast. Wind SW 5-15 MPH.

FRIDAY NIGHT: Clouding up. Rain late evening / overnight. Patchy fog. Lows 54-61. Wind variable to N up to 10 MPH.

SATURDAY: Cloudy with rain early, then variably cloudy with a chance of showers and thunderstorms. Highs 61-68. Wind variable to N up to 10 MPH.

SATURDAY NIGHT: Clouds re-thicken with another round of widespread showers overnight. Patchy fog. Lows 54-61. Wind N to variable up to 10 MPH.

SUNDAY: Clouds and showers very early, then a sun/cloud mix. Highs 66-73. Wind W 5-15 MPH.

SUNDAY NIGHT: Clearing. Lows 51-58. Wind W 5-15 MPH.

MONDAY: Mostly sunny. Highs 62-69. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 3-7)

Fair weather and a warm-up into the middle of next week. Watch for a shower threat with a frontal boundary from the north late week which may introduce a cooler maritime air mass, but this outlook is quite uncertain at this point.

DAYS 11-15 (JUNE 8-12)

Hints of weak blocking and a round or two of unsettled weather, but details impossible this far in advance. No major temperature departures anticipated.

  1. Good morning and thank you TK.

    Headed out to do some fishing this morning.
    A PERFECT morning for it. We’ll see how that translates
    to my catch. 🙂

    I was worried I might get wet, but doesn’t look that way now.

  2. Thank you TK. Currently 58F with my over / under being 62F today. Some northeast wind will keep it a little cooler for me.

  9. Thanks TK.

    Another lovely Saturday/Sunday combo in SNE. I guess at least it’s not in the 40’s like last week so I guess rain and 60’s and 70’s is somewhat better. Lol

    Heading to Italy next Sunday so hopefully we get some warm to hot weather. Will be nice for a change 🙂

  12. https://www.pivotalweather.com/model.php?m=hrrr&p=lgtden&rh=2025052912&fh=46&r=us_ne&dpdt=&mc=

    I so wish I’d have posted this for the northeaster.

    The above is the one for Saturday morning and it looks EXACTLY like the one for the noreaster and we know how much tstorm activity in SE Mass there was.

    By the way, lightning non-withstanding, impressive run on 12z HRRR. Rapidly intensifying system with again an impressive setup at all levels of the atmosphere and intensifying with time.

  15. TS Alvin is the second-latest first-named storm of the season in the EPAC.

  16. Good afternoon and thank you TK.

    It was a perfect morning for fishing weather-wise and the fish cooperated. Caught 37 fish, including 10 large mouth bass and 3 brook trout among a bunch of blue gills and a yellow perch.
    I can’t believe how perfect the weather was. Didn’t rain a drop with only a virtually non-discernible mist the last 1/2 hour of fishing that didn’t get me wet in the slightest.

    Saturday morning looks Brutal!!!1 YUCK!!!

    3. Only for a couple hours with a batch of showers / t-storms. By mid morning I think it’s quite nice.

  17. Just curious how much rain you are expecting this weekend for the Natick area. The timing looks good so most activities can take place. Wondering about afternoon golf. Thanks.

    1. It’s more about timing than amounts. Though amounts won’t be excessive.

      I think Saturday is dry 75% of the day. Late morning-midday golf is probably best bet. I think Sunday is 95% dry with showers having occurred mostly prior to sunrise.

  19. 12z Euro and 12z HRRR look similar to me for Friday night into Saturday morning and then again for a followup disturbance Saturday overnight.

    I like a blend of those 2 models.

  23. No changes. Still leaning (a bit more heavily) toward the western track for the first low and a quick end to the rain early Saturday. Second system – largely pre-dawn Sunday.

    Yesterday I hinted at this. Today, it’s more than a hint.

  24. Few things of note for areas besides New England.

    1. Tropical Storm Alvin has formed in the Pacific. Likely doesn’t reach hurricane strength, and probably dissipates before reaching western Mexico. However, the remnant moisture will get pulled up into the Southwest, and likely into a developing low that produces some severe weather in the Plains and Midwest Monday-Tuesday.

    2. The wildfires burning in Canada will send some fairly thick smoke into the Northern Plains and Great Lakes over the next 24-48 hours. A lot of it will get washed out before reaching the East Coast, but don’t be surprised if it is a little hazy around here if we get some sun Saturday afternoon or again on Monday.

    3. Huge plume of Saharan Dust will make its way into and across the Caribbean this weekend and early next week, reaching the Gulf by the end of the week. This suppresses any thunderstorm activity, cools the water a little due to less solar radiation getting in, but increases temperatures over land areas due to the lack of cloud cover and shower activity.

    4. Behind that Saharan Dust, ensembles still showing the possibility of a tropical spinning up in the western Caribbean or the Gulf. Bu that wouldn’t be until next weekend at the absolute earliest.

    1. I had read about this. There were warning signs. Last I read there was one person unaccounted for.

    3. While glacial calving is a normal occurrence, this one was in a location that doomed the village. But this is why they evacuated it before the event. It was known for a while it was coming “soon”.

      Not sure what the circumstances are surrounding the one missing person as nobody was supposed to be there.

  26. SClarke…may be too late to ask. How you do with today’s wordle. It may have been the oddest word yet
